ESH6T-USB: setup ASC0 from inside the MIDlet ... is it possible? | Thales IoT Developer Community

To setup ASC0 I use the common way: to send (with PuTTy in my case) the AT commands related to serial Interface (AT^SPOW, AT\Q0, AT+IPR, AT+ICF . Some of them need to use AT&W ) over ASC0 .
Everything works fine but...
In my case, this way involve a heavy task over more than 200 units.
Is there a way to setup ASC0 from inside the MIDlet?
Remember (or realize) that AT commands related to serial Interface make no sense to AT Command API
(Reference: Java User’s Guide -> 5.6.4 Configuration of Serial Interface (ASC0, ASC1))
By the way...
My goal is to send/receive data to/from serial device coupled by ASC0 to EHS6T-USB
To achieve that , I use javax.microedition.io.CommConnection (the usual way) inside the MIDlet code
Consider that I tested empirically that it's not enough to set properly the comm_connection_string and use the open method of javax.microedition.io.CommConnection.
Synchronization must exist between the real settings of ASC0 and comm_connection_string.
